Roland Truslove, John Allen Howe and Frank R. Cana, 1911 Encyclopædia Britannica (1911)
“ The officers of the army are obtained partly from the old-established military schools, partly from the ranks of the non-commissioned officers, the proportion of the latter being about one-third of the total number of officers. Artillery and engineer officers come from the École Polytechnique, infantry and cavalry from the École spéciale militaire de St-Cyr. Other important training institutions are the staff college (École supérieure de Guerre) which trains annually 70 to 90 selected captains and lieutenants ”
